DOOR-HANGER.

Specification of Letters Patent.

Patented Feb. 11, 1919.

Application filed May 13, 1918. Serial No. 234,074.

To all whom it may concern:

Be it known that I, CONRAD E. OEDER BORG, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Door-Hangers, of

p which the following is a specification.

My invention relates to door hangers, and is particularly adapted for the doors of elevators, although it may be used for any type of sliding door where vertical adjustment is desirable from time to time.

It will be understood that both therdoor and the supporting structure itself are apt to sag or become distorted as time goes on and thus prevent, or at least render difiicult, the proper operation of the door. In elevators particularly it is desirable that the door hang truly, for it is opened and closed with great frequency, and hence must be in proper operating trim. Furthermore, such doors usually have automatic latching devices which will .be rendered uncertain in their operation if the door is any way out of order.

The principal object of my invention is to provide a hanger of simple construction by the aid of which adjustments may be readily made.

Another object is to provide a construction by which the door may be readily unshipped and removed, but will nevertheless be safely held on its mountings unless a deliberate attempt is made to remove the door.

I obtain my objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a face view of the device;

Fig. 2 is an edge View thereof Fig. 3 is a vertical axial section; and

Fig. 4 is a perspective view showing the relationship of the two principal parts of the device.

Similar numerals refer to similar parts throughout the several views.

The device consists of two principal membersthe track member 1, which is provided with a roller 2 adapted to run on the track 3 and the door member 4 which has a ledge 5 at the bottom adapted to be bolted or otherwise fastened to the top of the door 6. These members 1 and 4 are in the main in the form of plates adapted tocontact each other when in use. The door member has two brackets 8 which are arranged horizontally and are vertically apertured to take set-screws 9, the lower ends whereof rest upon brackets 10, formed upon the track member. The weight of the door is thus carried by the set-screws resting upon the brackets 10.. The body of the track member rises above the top of the bracket 10, thus forming two lugs 12 which lie between the set-screws 10and the inner face of the door member. The'result is that the door mem ber cannot be moved away from the track member without first lifting it sufliciently to permit thelower ends of the set-screwsto clear the upper edge of the lugs 12. Said lugs and the set screws, therefore, constitute means for holding the two plates adjacent to each other when the device is in use. A vertical slot 15 is formed in the door member for receiving the rib 16 formed on the track member 1. These parts fit slidingly so that relative movementin a vertical direction is permitted but relative movement in the plane of the members is prevented. Said rib 16 projects down below the bottom of the main body of the door member 1, viz. at the point 16 and thus passes behind the ledge 5 and helps to keep the two members from parting from each other in a direction perpendicular to the plane of the plates.

The operation of the device will now be readily understood. In ordinary installations there will be one of these hangers at each end of the door, that is, one near the front and one near the back edge. The door members will be fastened to the top of the door and the rollers 2 of the track members will travel upon the stationary track 3. The parts will be assembled, as shown, with the result that the door member 4: may be readily raised or lowered upon the track member by merely screwing the set-screws 9 in the proper direction up or down.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A door hanger having a door member adapted to be secured to the door, and a track member adapted to travel upon a supporting track, the door member resting upon the track member, the door member having a vertical slot and the track member a vertical rib fitting slidingly into said slot, the door member having a ledge crossing said slot and the rib being extended vertically to pass behind said ledge for preventing relative movement of the parts transversely to the plane of the door. 7

2. A door hanger having a door membercomposed of a late .havinga ledge project ing horizontally from 1t for attachment to the top of the door, said member also hav- 5 ing a vertical slot passing behind said ledge,

atrackmember having a vertical Surface contacting a correspondingsurface on the door member, said track member being adapted to run upon a trackand support the door member, sald track member having a vertical rib fitting slidingly in said slot and extended down beyond the lower end of the track member for preventing the door member from parting from the track member.

' v3. A door hanger comprising a track member adapted to travel upon a track, a

I 7 door member adapted to support the door,

the door'member having a vertically arranged set screw adapted to rest upon the trackmember, and a flange on said track member disposed bfitween the set screw and the body of the door member for holding the parts assembled.

4:. A door hanger comprising .a member, a door member having a vertically arranged adjusting screw resting upon the track member, a flange on the track member for engaging the screw to hold the parts as.- sembled, the door member being vertically slotted and having aledge passing across said slot, and a rib on the track member fitting slidingly in the slot and having a downtrack 7 ward extension passing behind the ledge for cooperating with said flange to hold the parts assembled.

In witness whereof, I have hereunto subscribed my name.
